"Rapidly optimized propellers for every drone"

Your mission demands more than a standard propeller.

We deliver ultra-precise, mission-optimized drone propellers engineered through 3D-printed molds and advanced carbon composite technology—surpassing the limitations of traditional metal tooling.

Faster production, agile customization, and performance tailored to your mission environment—
from low-noise operation to crosswind stability and long-range endurance.

Silent Sky is

Design and manufacture customized drone propellers tailored to the specific demands of each mission—
from Urban Air Mobility (UAM) and VTOL aircraft, to agricultural spraying, aerial surveillance, logistics and delivery, search and rescue, and even personal hobby drones.

By analyzing the unique flight requirements of each application, we engineer propellers optimized for low noise, high thrust, durability, and endurance.

UAM (Urban Air Mobility)

Engineered for Reliability and Repetitive Flights

Urban air mobility involves high-risk, manned operations where safety is paramount. Our custom-designed propellers offer a unique combination of ultralight construction and structural rigidity, ensuring both low noise and stability under repetitive takeoffs and landings.

Agricultural Spraying Drones

Key to Operational Efficiency and Precision Spraying

For large-area coverage and repeated operations, agricultural drones need long-endurance performance and stable dispersion control. Our blades are engineered to resist wind turbulence and payload fluctuations, enhancing spray accuracy and improving field productivity.

Logistics & Delivery Drones

Optimized for Payload Handling and Route Consistency

Delivery drones require precision engineering to carry payloads ranging from 1–5 kg and beyond, while maintaining stable long-range flight. We tailor each propeller’s pitch, mounting method, and motor compatibility to meet the specific demands of your delivery platform.

Military & & Rescue Drones

Custom-Designed for Ultra-Low Noise Flight

Noise is a critical factor in mission success.
Our propellers are engineered to minimize acoustic signatures, enabling stealthy and stable operations in urban, night-time, and high-risk environments.

We envision a future where drone propulsion is no longer limited by tooling delays or design constraints.

By harnessing advanced 3D-printed mold technology, we accelerate the development and manufacturing of custom drone propellers—delivering flight-ready solutions with unmatched speed and flexibility.

We continuously push the boundaries of acoustic optimization, crosswind stability, and aerodynamic precision, ensuring every propeller we produce is engineered for real-world performance.

Custom Propeller Development Workflow

Fast, precise, and mission-specific. From idea to flight.
